Tools from practice.

Free tools I use in my own engagements. No sign-up, no data collection, no affiliate links — everything runs in the browser or is publicly documented.

● For whom

SEO operators, CMOs and editorial teams looking for concrete, operationally usable tools — not yet another marketing tool stack.

● Promise

GDPR-compliant, no server uploads, no IP logs. What stays in the browser stays in the browser.

● Methodology

All scores and formulas are based on 500+ documented enterprise audits. Weights are transparent.

The six tools below cover the most common entry-level questions: How GEO-ready is my site? How do you write valid Schema.org JSON-LD? Which technical terms matter in 2026? What does the current market data show? If you do not find the right tool here, write to me directly — I add new ones regularly.
